Plumber A charges $25 for a house call and $50 for each hour spent on the job. Plumber B charges $35 for a house call and $45 for each hour spent on the job. If your job will take 4 hours to complete, which plumber should you use? How much will it cost you?

Plumber B at a cheap price of $215

Step-by-step explanation:

Plumber A charges $25 for a house call and $50 for each hour that is spent on the job

Plumber B charges $35 for a house call and $45 for each hour that is spent on the job

It will take 4 hours to complete the job

Plumber A

= $25 + 4×50

= $25 + 200

= $225

Plumber B

= $35 + 4(45)

= $35 + 180

= $215

Hence I would use plumber B because it will cost me a cheaper price of $215

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
